Prime Intellect vs E2B

Prime Intellect runs each sandbox in a hardware-isolated microVM, with pause and resume that keeps memory and processes, checkpoints you can fork, and thousands of sandboxes starting at once. Built for RL rollouts, evals and agent fleets. A 2 vCPU / 4 GiB sandbox lists at $0.090 an hour on Prime Intellect against $0.166 on E2B, 46% less.

Prices are list prices for one hour of a 2 vCPU / 4 GiB sandbox: 2 × the vCPU rate + 4 × the memory rate. Each value links to the page it came from; not published means the vendor states no figure. How we compare.

Pick Prime Intellect instead of E2B when

your bill is the problem: the same 2 vCPU / 4 GiB box lists at $0.090 an hour here against $0.166 on E2B, 46% less (launch rate, valid through 22 December 2026).
your agents run longer than E2B's 24-hour Pro session cap: 60 min default, no lifetime limit when set.

Stay on E2B when

you need a SOC 2 report: E2B states Type II, and Prime Intellect states none in our data.
you want managed cloud, your own cloud account and self-hosting from one vendor: E2B offers all three, with BYOC on its Enterprise plan.

All Prime Intellect facts

Source per value

Isolation Isolation technology the vendor states for each sandbox.: microVM 1
Other isolation options Alternative runtimes the vendor offers besides the default (e.g. VM runtime, gVisor for GPU).: Not published
Deployment Managed cloud service, self-hosted software, or both.: managed 1
Billing basis What the meter counts: wall-clock allocated resources, active CPU only, requests/plan quota, session-hours, or free software.: wall clock 2
vCPU price $/vCPU-hr Published on-demand CPU rate normalised to USD per vCPU-hour (per-second rates multiplied by 3,600; per-core rates divided by vCPUs per core where the vendor defines it). Lowest public tier, default region. 0 means the vendor states no separate CPU charge.: $0.02 2
Memory price $/GiB-hr Published memory rate normalised to USD per GiB-hour (GB treated as GiB where the vendor does not distinguish). 0 means the vendor states memory is free.: $0.0125 2
Sandbox from $/sandbox-hr Smallest published per-sandbox hourly price, where the vendor publishes one.: $0.0335 1
Paid plan from $/mo Cheapest paid platform plan fee (before usage).: Not published
Free tier A free plan, free monthly allowance or sign-up credit exists.: Not published
Free tier detail What the free tier or credit includes, as published.: Not published
Cold start ms Vendor-published create/boot time in milliseconds (a vendor claim, not our benchmark). Only filled when the vendor publishes a number; see startup_claim for percentile and conditions.: Not published
Resume time ms Vendor-published resume-from-pause/standby/snapshot time in milliseconds.: Not published
Startup claim The vendor's startup/resume wording with conditions, quoted or closely paraphrased.: "Thousands start within seconds" (no per-sandbox figure) 1
Max session length Longest single sandbox session by plan, as published.: 60 min default, no lifetime limit when set 2
Persistence / snapshots Filesystem state can be kept between runs (snapshots, persistent disks, volumes).: Yes 2
Pause / resume A sandbox can be paused, suspended, hibernated or put in standby and resumed later.: Yes 2
Memory state kept Pause/hibernate preserves running memory state, not only the filesystem.: Yes 2
Fork / branch A running or snapshotted sandbox can be cloned into new sandboxes.: Yes 2
GPU GPU sandboxes are offered.: No 2
Self-host Can run on your own hardware or cluster (open source or licensed).: Not published
BYOC / VPC Vendor-managed deployment inside your own cloud account.: Not published
Open source Core sandbox runtime is published under an open-source licence.: Not published
Licence Open-source licence of the runtime, if any.: Not published
SDKs / languages Official SDK languages (or supported execution languages where noted).: Python, CLI (prime) 2
Regions Published regions or region count.: Not published
Max vCPU per sandbox vCPU Largest published vCPU count per sandbox on any self-serve or enterprise plan.: 16 2
Max memory per sandbox GiB Largest published memory per sandbox.: 64 2
Concurrency Published concurrent sandbox limits by plan.: 1,024 active sandboxes (default account limit) 2
SOC 2 SOC 2 status as stated by the vendor.: Not published
HIPAA Vendor offers HIPAA-compliant usage/BAA (on any plan).: Not published
2 vCPU + 4 GiB per hour $/hr Hourly list price of one 2 vCPU / 4 GiB sandbox: 2 x the vCPU rate + 4 x the memory rate, from the two published rates. Left empty for self-hosted software and for vendors without both rates. Vendors that bill CPU only while busy (Vercel, Cloudflare, Upstash, Tensorlake, AWS AgentCore) cost less for idle agents than this shows.: $0.09 1
Price vs E2B x E2B The 2 vCPU + 4 GiB hourly price divided by E2B's own ($0.1656 at $0.000014/vCPU-s and $0.0000045/GiB-s). Under 1 is cheaper than E2B.: 0.54 1
Status Preview, experimental, beta, sunset or self-hosting caveats the vendor documents.: Not published

Pricing model: usage
From: $0.02 vCPU-hour
Pricing note: Launch rates valid through 22 December 2026: $0.02/vCPU-h, $0.0125/GiB-h, disk $0.0002/GiB-h, billed while running; a paused sandbox pays for disk only. 1 vCPU / 1 GiB / 5 GiB disk = $0.0335/h. Images and checkpoints $0.10/GiB-month. GPUs "coming soon". Pricing checked 2026-11-09.
